Review
The nail unit is the most commonly affected area in hand infections, which can be primary infection or superinfection complicating other nail or skin disorders. Trauma, mechanical or chemical, is usually the trigger enabling infiltration of infectious organisms. Artificial nails and nail polish are also a possible cause of bacterial infection, harboring microorganisms. In severe acute bacterial infection, surgical intervention is often needed to prevent morbidity and disability. Abscess should always be drained, but viral infection such as herpetic whitlow, may mimic an abscess and, in contrast, requires non-operative treatment; to prevent sequelae. A more conservative approach is also generally advisable in less severe bacterial infection, other viral infections and in subacute or chronic nail infection. The present review deals with acute, subacute and chronic bacterial and viral infections of the nail unit, with a focus on diagnostic and treatment options. LEVEL OF EVIDENCE: III, systematic review of level III studies.

INTRODUCTION
Cuticle reduction and removal techniques are commonly performed by nail technicians for nail cosmesis. However, manipulation of the nail cuticle can lead to localized infection and nail dystrophy.
CASE PRESENTATION
In this case, a 20-year-old woman from the Philadelphia area in the USA presented with onychomadesis secondary to acute paronychia following a "Russian" manicure. In this technique, an electronic filer is used to completely remove the cuticle, leaving the proximal nail fold exposed and vulnerable.
CONCLUSION
As this style of manicure is being inaccurately publicized as safe, it is important that dermatologists are aware of this technique and educate our patients about its potential for harm.

INTRODUCTION
Symptoms of pemphigus vulgaris (PV) rarely include nail findings. When ungual involvement does occur, the most common manifestations are paronychia and onychomadesis. Onycholysis is very uncommon, and complete nail loss has not been reported in the literature. Ungual involvement is thought to be closely correlated with disease severity, with only severe PV cases demonstrating nail symptoms.
CASE PRESENTATION
We report a case of a 34-year-old female presenting with mild to moderate PV yet severe onycholysis of her first toe leading to secondary nail loss in conjunction with paronychia of her bilateral thumbs. Oral tofacitinib and rituximab infusions led to strikingly rapid improvement in her nail symptoms.
DISCUSSION/CONCLUSION
This case illustrates the importance of a thorough history and physical exam, as a primary complaint of nail symptoms in these patients may lead to unrecognized PV by even the most skilled practitioners. Tofacitinib and rituximab in combination may rapidly improve nail involvement.

INTRODUCTION
Paronychia is the most common hand infection. Prior paronychia studies were limited by small patient numbers. We conducted a national-level analysis over two decades, analyzing demographics, etiologies, and trends in paronychia cases.
METHODS
We conducted a retrospective analysis of paronychia cases in the 1999-2018 National Electronic Injury Surveillance System database. Sex, race, age, and cause were recorded and compared using χ, ANOVA, and tests. Multivariable linear regression analysis assessed changes in age, weight, and sex over time.
RESULTS
We analyzed a total of 2,512 cases, with an average age of 27.6 ± 20.6 years, 45.5% females, and 25.6% white and 28.6% black patients. In multivariable linear regression, both age and weight significantly increased over time. Manicuring was the most common etiology (30.9%), increasing in incidence over time and with a higher frequency in adults ( < 0.0001) and females ( < 0.0001). There was a significant decrease in pediatric paronychia cases over time, particularly in 0- to 4-year-olds. Possible limitations include missed paronychia cases or additional non-paronychia cases due to improper coding, infrequent race reporting, and inability to analyze treatments or distinguish between paronychia subtypes.
CONCLUSIONS
Paronychia cases were associated with increased age and weight over time with different presentations by age. Manicuring represents the largest growing paronychia etiology.

Familiarity with common nail disorders enables the clinician to diagnose and treat nail disorders and to recognize red-flag conditions. Knowledge of the anatomy of the nail unit is essential to understand the origin of nail disorders. This article focuses on neoplasms, abnormalities of nail color and shape, infections, and inflammatory conditions of the nail unit. There are various neoplasms of and around the nail unit, like squamous cell carcinoma (in situ), melanoma, and benign neoplasms such as mucous cyst, subungual exostosis, glomus tumor, onychopapilloma and fibro(kerato)ma. The most common deviating colors of the nail are red, white and brown-black. Abnormalities of nail color and shape may indicate an underlying systemic disease. Infections of the nail unit include onychomycosis, acute paronychia, pseudomonas nail infection and verruca vulgaris. The inflammatory conditions we discuss in this article are chronic paronychia, psoriasis, alopecia areata and lichen planus.

The development of targeted therapy has improved treatment outcomes for patients with non-small cell lung cancer (NSCLC). However, paronychia, a common adverse effect of targeted therapy, remains burdensome. Although conservative treatments for paronychia have been well reported in the literature, studies on the efficacy of surgical partial matricectomy for paronychia, are scarce. This study aimed to evaluate the effect of surgical partial matricectomy in targeted therapy-induced paronychia in patients with NSCLC. This retrospective cohort study included 11 patients with a total of 18 lesions on the big toes. Data on lung cancer stages, types and duration of targeted therapy, onset of paronychia, pain scale scores, conservative treatments, course of matricectomy, paronychia-free interval after matricectomy, and wound condition were collected from medical records. The Wilcoxon signed-rank test was used for analysis. The mean pain scale score after matricectomy was significantly lower than that after conservative treatments (1.00 ± 0.00 vs 2.94 ± 0.87; P < .001) and before treatment (1.00 ± 0.00 vs 3.06 ± 0.80; P < .001). The mean duration of matricectomy was significantly shorter than that of conservative treatments (3.22 ± 1.00 vs 56.56 ± 52.29 weeks; P < .001). Surgical partial matricectomy is an effective and enduring intervention for targeted therapy-related paronychia. It provides a shorter course of treatment, reduced pain, and improved appearance of the healed wound. Furthermore, surgical partial matricectomy could result in a better quality of life during targeted therapy than that of conservative treatments.

Randomized Controlled Trial
BACKGROUND
Treatment of onychomycosis is challenging by virtue of the impact of nail disfigurement, the location of the fungi within the nail and reported antifungal resistance worldwide. Light-based technologies are promising primary or adjunctive therapeutic modalities. We aimed to compare the efficacy of photodynamic therapy and fractional CO2 laser monotherapy either alone or in combination for onychomycosis.
PATIENTS AND METHODS
This prospective randomized comparative study was conducted on 51 onychomycosis patients divided into three groups. In group A, patients were treated using 6 photodynamic therapy sessions using methylene blue and IPL (560 to 700 nm, fluence 12 J/cm2). Group B patients were treated using 6 bimonthly fractional CO2 laser sessions (10,600 nm, 1.600 mj energy and 0.6 mm density) and group C patients were treated using 6 combined fractional CO2 laser and photodynamic therapy sessions. Patients were evaluated mycologically, dermoscopically and clinically by calculation of proximal nail diameter percentage at baseline, monthly, at the end of treatment and after a 6-month follow-up period post-treatment.
RESULTS
Candida was the most commonly isolated organismin in 64.7%, 70.6% and 70.6% of the pateints in groups A, B and C, respectively. The dermoscopic findings in the total dystrophic onychomycosis was subungual hyperkeratosis in 6 patients (100%), longitudinal streaks and striae in 1 patient (16.7%). In dorsolateral subungual onychomycosis, jagged proximal edge in 31 patients (70.5%), and pigmentation in 30 patients (68.2%) were noted. In proximal subungual onychomycosis irregular matt patches were seen in 1 patient (100%). Proximal nail diameter percentage showed statistically significant improvement after treatment and 6 months follow up in the 3 studied groups. Mean increase of proximal nail diameter after treatment was highest in group C (52.94 ± 20.24), followed by group B (43.82 ± 21.03) and least in group A (35.29 ± 17.0). This difference was statistically significant (p = 0.044). Reported side effects were mild-moderate pain, discoloration and paronychia.
CONCLUSION
We conclude that fractional CO2 laser and photodynamic monotherapy, and their combination achieve high success rates, good patient satisfaction and safety profile. Fractional CO2-assisted photodynamic therapy is associated with the highest improvement over either fractional CO2 or photodynamic therapy alone.

Common autoimmune bullous diseases (AIBDs) include pemphigus and bullous pemphigoid (BP), which are primarily caused by IgG autoantibodies against the structural proteins of desmosomes at the cell-cell junction and hemidesmosomes at the epidermal-dermal junction. Few studies have assessed nail changes in patients with pemphigus or BP. In the present study, we collected the clinical data of 191 patients with AIBDs (108 patients with pemphigus and 83 patients with BP) and 200 control subjects. Nail changes were observed in 77.0% (147/191), 77.8% (84/108), and 75.9% (63/83) of patients with AIBDs, pemphigus, and BP, respectively, and 14.5% (29/200) of control subjects. Beau's lines and paronychia were the most common nail involvement, observed in 22.5% (43/191) and 22.5% (43/191) of patients with AIBDs, 25.0% (27/108) and 25.9% (28/108) of patients with pemphigus, 19.3% (16/83) and 18.1% (15/83) of patients with BP, respectively. The autoimmune bullous skin disorder intensity score (ABSIS) and the onset time of patients with pemphigus or BP with nail changes were different. Onychomycosis accounted for 21.5% (41/191) of all patients with AIBDs. The ABSIS was correlated with nail involvement in patients with BP ( = 0.46, < 0.001), and weakly correlated with nail involvement in patients with AIBDs ( = 0.37, < 0.001), pemphigus ( = 0.29, = 0.009), and pemphigus vulgaris (PV; = 0.35, = 0.008). No correlation was observed between nail involvement and disease antibody titers. In conclusion, nail changes are frequently observed in patients with pemphigus and BP. The type and onset time of nail changes may indicate the severity of pemphigus and BP, which warrants the attention of dermatologists.
